    The percentage of participants treated with investigational drug who experience such an event.

    Percentage of participants with treatment-emergent adverse events assessed as drug-related by the investigator are reported.

    Percentages are calculated using total number of participants per treatment as the denominator.

    Measured: From 1st drug administration on Day 1 till Day 19 + 16 days Residual Effect Period (REP), up to 35 days.

    The area under the concentration-time curve of the BI 706321 in plasma over the time interval from 0 extrapolated to infinity (AUCR0-∞) after the first dose administration is reported.

    Measured: Within 3 hours prior to administration and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24 hours, and 1.5, 2, 3, and 4 days after first BI 706321 administration.

  2. Single-Dose Part: Maximum Measured Concentration of BI 706321 in Plasma (Cmax)

    The maximum measured concentration of BI 706321 in plasma (Cmax) after the first dose administration is reported.

    Measured: Within 3 hours prior to administration and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24 hours, and 1.5, 2, 3, and 4 days after first BI 706321 administration.

    The accumulation ratio based on Cₘₐₓ (Rᴀ,ᴄₘₐₓ,ₛₛ) shows how much the drug concentration increases at steady state compared to the first dose. It is calculated as a ratio of Cₘₐₓ at steady state (Cₘₐₓ,ₛₛ) and Cₘₐₓ after the first dose (Cₘₐₓ).

    Rᴀ,ᴄₘₐₓ,ₛₛ = Cₘₐₓₛₛ/Cₘₐₓ.

    The accumulation ratio based on AUC₀-ₜ (Rᴀ,ᴀᴜᴄ₀-ₜ,ₛₛ) shows how much the total drug exposure over a uniform dosing interval τ increases at steady state compared to the first dose. It is calculated as a ration of AUC₀-ₜ at steady state (AUC₀-ₜₛₛ) and AUC₀-ₜ after the first dose (AUC₀-ₜ).

    Rᴀ,ᴀᴜᴄ₀-ₜ,ₛₛ = AUC₀-ₜₛₛ/AUC₀-ₜ.

    Measured: Within 3 hours prior to administration and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 24 hours, and 1.5, 2, 3, and 4 days, and additional time points up to 26 days after first BI 706321 administration.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing BI 706321 in people with Healthy, run by Boehringer Ingelheim at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 23 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Drug-related Adverse Events (time frame: From 1st drug administration on Day 1 till Day 19 + 16 days Residual Effect Period (REP), up to 35 days.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2025; AzTrials last refreshed its copy on 7 Nov 2026.
